 Analyse the different heat retention capabillities of straw, sand, paper and clothThe purpose of this experiment was to find out the effect of different types of insulation on heat retention. My hypothesis is that sand will retain more heat than straw, sand, paper, clothâ€™ batting.

 Convection: How does temperature affect the movement of water?Convection is the phenomena characterized by the movement of molecules in gases and liquids. Heat causes molecules to be active, while cooler temperatures result in less activity. Convection can be observed in volcanoes, in the ocean, in cooking, in heating your home and even in decorative lava lamps. In this awesome science fair project you will observe how temperature changes lead to convection

 Do different brands of sunscreen have different strengths?I wanted to know if SPF matters when you buy sun block. For example, does a CVS brand 30 sunblock work better than a CVS brand 15 sunblock? I also wanted to know if higher priced sunblock works better than lower priced sunblock of the same SPF? My hypothesis was that the higher the SPF the better it would protect and that higher priced sun block would work better than lower priced.

 Do different gases expand differently when heated?The purpose of this experiment was to compare the amount of heat expansion in various gases. The information gained from this experiment will determine what temperature you need to keep your balloons at so that it can have more volume.

 Do different types of firewood produce different amounts of heat?This experiment was done to find out whether different types of firewood will burn at different temperatures. The results will help us to choose the ideal type of wood to use in campfires or outdoor cooking.

 Does black or white color absorb light better?The purpose of the following experiment is to demonstrate that energy from the sun can be collected and stored in many ways. In particular, it demonstrates the difference in the rate of absorption between black and white colors.

 Does the brightness of a bulb vary when different gases are used to fill the bulb?The purpose of this experiment is to determine if the type of gas inside a light bulb has any effect on the brightness of the bulb, and if so what type of gas produces the brightest bulb.
Difficulty: High school
 Does the color of your hair affect its ability to keep your head warm?The purpose of the experiment was to determine if the shade of human hair has an effect on its ability to insulate the human body. Based on background information, the hypothesis of the experiment was that darker shaded hair would insulate better than light shaded hair.
Difficulty: Elementary school
 Does wind increase the rate of evaporation?The purpose of this experiment is to determine if fans really cool the body and its temperature, I believe that the fan will evaporate the water it is blowing on, which is acting like perspiration on skin. The humid layer should be replaced by a dryer, cooler layer. The water in the pan which the air current is blowing on should evaporate quicker than the second pan, and it should be cooler than t
